Other causes of corneal ulcers include: Abrasions or burns to the cornea caused by injury to the eye. Scratches, scrapes and cuts from fingernails, paper cuts, makeup brushes and tree branches can become infected by bacteria and lead to corneal ulcers. Burns caused by caustic chemicals found in the workplace and at home can cause corneal ulcers.
Risk factors for the development of corneal ulcer include having had a prior corneal ulcer, failing to wear eye protection when using power tools or during welding, having extremely dry eyes, misusing contact lenses, failing to treat a red eye, exposure to UV light (snow blindness), and abnormalities of the eyelids or lashes.
